On the extended mind hypothesis (EM), many of our cognitive states and processes are hybrids, unevenly distributed across biological and nonbiological realms. In certain circumstances, things - artifacts, media, or technologies - can have a cognitive life, with histories often as idiosyncratic as those of the embodied brains with which they couple. The realm of the mental can spread across the physical, social, and cultural environments as well as bodies and brains. My independent aims in this chapter are: first, (...) to describe two compatible but distinct movements or "waves" within the EM literature, arguing for the priority of the second wave (and gesturing briefly toward a third); and, second, to defend and illustrate the interdisciplinary implications of EM as best understood, specifically for historical disciplines, by sketching two case studies.

Evolutionary theory is undergoing an intense period of discussion and reevaluation. This, contrary to the misleading claims of creationists and other pseudoscientists, is no harbinger of a crisis but rather the opposite: the field is expanding dramatically in terms of both empirical discoveries and new ideas. In this essay I briefly trace the conceptual history of evolutionary theory from Darwinism to neo-Darwinism, and from the Modern Synthesis to what I refer to as the Extended Synthesis, a more inclusive conceptual (...) framework containing among others evo–devo, an expanded theory of heredity, elements of complexity theory, ideas about evolvability, and a reevaluation of levels of selection. I argue that evolutionary biology has never seen a paradigm shift, in the philosophical sense of the term, except when it moved from natural theology to empirical science in the middle of the 19th century. The Extended Synthesis, accordingly, is an expansion of the Modern Synthesis of the 1930s and 1940s, and one that—like its predecessor—will probably take decades to complete. (shrink)

This paper introduces a new, expanded range of relevant cognitive psychological research on collaborative recall and social memory to the philosophical debate on extended and distributed cognition. We start by examining the case for extended cognition based on the complementarity of inner and outer resources, by which neural, bodily, social, and environmental resources with disparate but complementary properties are integrated into hybrid cognitive systems, transforming or augmenting the nature of remembering or decision-making. Adams and Aizawa, noting this distinctive (...) complementarity argument, say that they agree with it completely: but they describe it as “a non-revolutionary approach” which leaves “the cognitive psychology of memory as the study of processes that take place, essentially without exception, within nervous systems.” In response, we carve out, on distinct conceptual and empirical grounds, a rich middle ground between internalist forms of cognitivism and radical anti-cognitivism. Drawing both on extended cognition literature and on Sterelny’s account of the “scaffolded mind” (this issue), we develop a multidimensional framework for understanding varying relations between agents and external resources, both technological and social. On this basis we argue that, independent of any more “revolutionary” metaphysical claims about the partial constitution of cognitive processes by external resources, a thesis of scaffolded or distributed cognition can substantially influence or transform explanatory practice in cognitive science. Critics also cite various empirical results as evidence against the idea that remembering can extend beyond skull and skin. We respond with a more principled, representative survey of the scientific psychology of memory, focussing in particular on robust recent empirical traditions for the study of collaborative recall and transactive social memory. We describe our own empirical research on socially distributed remembering, aimed at identifying conditions for mnemonic emergence in collaborative groups. Philosophical debates about extended, embedded, and distributed cognition can thus make richer, mutually beneficial contact with independently motivated research programs in the cognitive psychology of memory.

We present a specific elaboration and partial defense of the claims that cognition is enactive, embodied, embedded, affective and (potentially) extended. According to the view we will defend, the enactivist claim that perception and cognition essentially depend upon the cognizer’s interactions with their environment is fundamental. If a particular instance of this kind of dependence obtains, we will argue, then it follows that cognition is essentially embodied and embedded, that the underpinnings of cognition are inextricable from those of affect, (...) that the phenomenon of cognition itself is essentially bound up with affect, and that the possibility of cognitive extension depends upon the instantiation of a specific mode of skillful interrelation between cognizer and environment. Thus, if cognition is enactive then it is also embodied, embedded, affective and potentially extended. (shrink)

According to the Extended Mind thesis, the mind extends beyond the skull or the skin: mental processes can constitutively include external devices, like a computer or a notebook. The Extended Mind thesis has drawn both support and criticism. However, most discussions—including those by its original defenders, Andy Clark and David Chalmers—fail to distinguish between two very different interpretations of this thesis. The first version claims that the physical basis of mental features can be located spatially outside the body. (...) Once we accept that the mind depends on physical events to some extent, this thesis, though not obvious, is compatible with a large variety of views on the mind. The second version applies to standing states only, and has to do with how we conceive the nature of such states. This second version is much more interesting, because it points to a potential tension in our conception of minds or selves. However, without properly distinguishing between the two theses, the significance of the second is obscured by the comparative triviality of the first. (shrink)

Extended Cognition (EC) hypothesizes that there are parts of the world outside the head serving as cognitive vehicles. One criticism of this controversial view is the problem of “cognitive bloat” which says that EC is too permissive and fails to provide an adequate necessary criterion for cognition. It cannot, for instance, distinguish genuine cognitive vehicles from mere supports (e.g. the Yellow Pages). In response, Andy Clark and Mark Rowlands have independently suggested that genuine cognitive vehicles are distinguished from supports (...) in that the former have been “recruited,” i.e. they are either artifacts, or, products of evolution. I argue against this proposal. There are counter examples to the claim that “Teleological” EC is either necessary or sufficient for cognition. Teleological EC conflates different types of scientific projects, and inherits content externalism’s alienation from historically impartial cognitive science. (shrink)

Recent debates between proponents of the modern evolutionary synthesis (the standard model in evolutionary biology) and those of a possible extended synthesis are a good example of the fascinating tangle among empirical, theoretical, and conceptual or philosophical matters that is the practice of evolutionary biology. In this essay, we briefly discuss two case studies from this debate, highlighting the relevance of philosophical thinking to evolutionary biologists in the hope of spurring further constructive cross-pollination between the two fields.

The philosophical case for extended cognition is often made with reference to ‘extended-memory cases’ (e.g. Clark & Chalmers 1998); though, unfortunately, proponents of the hypothesis of extended cognition (HEC) as well as their adversaries have failed to appreciate the kinds of epistemological problems extended-memory cases pose for mainstream thinking in the epistemology of memory. It is time to give these problems a closer look. Our plan is as follows: in §1, we argue that an epistemological theory (...) remains compatible with HEC only if its epistemic assessments do not violate what we call ‘the epistemic parity principle’. In §2, we show how the constraint of respecting the epistemic parity principle stands in what appears to be a prima facie intractable tension with mainstream thinking about cases of propositional memory. We then outline and evaluate in §3 several lines of response. (shrink)

According to the view that has become known as the extended mind , some token mental processes extend into the cognizing organism’s environment in that they are composed (partly) of manipulative, exploitative, and transformative operations performed by that subject on suitable environmental structures. Enactivist models understand mental processes as (partly) constituted by sensorimotor knowledge and by the organism’s ability to act, in appropriate ways, on environmental structures. Given the obvious similarities between the two views, it is both tempting and (...) common to regard them as essentially variations on the same theme. In this paper, I shall argue that the similarities between enactivist and extended models of cognition are relatively superficial, and the divergences are deeper than commonly thought. (shrink)

This paper discusses two perspectives, each of which recognises the importance of environmental resources in enhancing and amplifying our cognitive capacity. One is the Clark–Chalmers model, extended further by Clark and others. The other derives from niche construction models of evolution, models which emphasise the role of active agency in enhancing the adaptive fit between agent and world. In the human case, much niche construction is epistemic: making cognitive tools and assembling other informational resources that support and scaffold intelligent (...) action. I shall argue that extended mind cases are limiting cases of environmental scaffolding, and while the extended mind picture is not false, the niche construction model is a more helpful framework for understanding human action.

This paper explores some of the differences between the enactive approach in cognitive science and the extended mind thesis. We review the key enactive concepts of autonomy and sense-making . We then focus on the following issues: (1) the debate between internalism and externalism about cognitive processes; (2) the relation between cognition and emotion; (3) the status of the body; and (4) the difference between ‘incorporation’ and mere ‘extension’ in the body-mind-environment relation.

For more than one decade, Andy Clark has defended the now-famous extended mind thesis, the idea that cognitive processes leak into the world. In this paper I analyse Clark’s theoretical justification for the thesis: explanatory simplicity. I argue that his way of justifying the thesis leads into contradiction, either at the level of propositional attitude ascriptions or at the theoretical level. I evaluate three possible strategies of dealing with this issue, concluding that they are all likely to fail and (...) that therefore, as regards explanatory simplicity, the burden of proof is on Clark’s side. The paper divides into two main sections: in “Simplicity and Coherence”, I define the two concepts that are important in this context (simplicity and explanatory coherence). In “How to Cope with Coherence”, these two concepts are applied to the central thought experiment, the Inga/Otto case. It will be shown that justifying the extended mind thesis by reference to simplicity may cause trouble, because ‘extended’ behavioural descriptions are likely to yield rather complicated explanations. (shrink)

The extended-mind thesis says that mental states can extend beyond one’s skin. Clark and Chalmers infer from this that the subjects of such states also extend beyond their skin: the extended-self thesis. The paper asks what exactly the extended-self thesis says, whether it really does follow from the extended-mind thesis, and what it would mean if it were true. It concludes that the extended-self thesis is unattractive, and does not follow from the extended mind (...) unless thinking beings are literally bundles of mental states. (shrink)

The extended mind hypothesis (Clark and Chalmers in Analysis 58(1):7–19, 1998; Clark 2008) is an influential hypothesis in philosophy of mind and cognitive science. I argue that the extended mind hypothesis is born to be wild. It has undeniable and irrepressible tendencies of flouting grounding assumptions of the traditional information-processing paradigm. I present case-studies from social cognition which not only support the extended mind proposal but also bring out its inherent wildness. In particular, I focus on cases (...) of action-understanding and discuss the role of embodied intentionality in the extended mind project. I discuss two theories of action-understanding for exploring the support for the extended mind hypothesis in embodied intersubjective interaction, namely, simulation theory and a non-simulationist perceptual account. I argue that, if the extended mind adopts a simulation theory of action-understanding, it rejects representationalism. If it adopts a non-simulationist perceptual account of action-understanding, it rejects the classical sandwich view of the mind. (shrink)

A new position in the philosophy of mind has recently appeared: the extended mind hypothesis (EMH). Some of its proponents think the EMH, which says that a subject's mental states can extend into the local environment, shows that internalism is false. I argue that this is wrong. The EMH does not refute internalism; in fact, it necessarily does not do so. The popular assumption that the EMH spells trouble for internalists is premised on a bad characterization of the internalist (...) thesis—albeit one that most internalists have adhered to. I show that internalism is entirely compatible with the EMH. This view should prompt us to reconsider the characterization of internalism, and in conclusion I make some brief remarks about how that project might proceed. (shrink)

This paper will defend the claim that, under certain circumstances, the material vehicles responsible for an agent’s conscious experience can be partly constituted by processes outside the agent’s body. In other words, the consciousness of the agent can extend. This claim will be supported by the Extended Mind Thesis (EMT) example of the artist and their sketchpad (Clark 2001, 2003). It will be argued that if this example is one of EMT, then this example also supports an argument for (...) consciousness extension. Clark (2009) rejects claims of consciousness extension. This paper will challenge Clark and argue that he fails to show that the material vehicles responsible for consciousness must be internal to the agent. (shrink)

This paper reformulates some of the questions raised by extended mind theorists from an enactive, life/mind continuity perspective. Because of its reliance on concepts such as autopoiesis, the enactive approach has been deemed internalist and thus incompatible with the extended mind hypothesis. This paper answers this criticism by showing (1) that the relation between organism and cogniser is not one of co-extension, (2) that cognition is a relational phenomenon and thereby has no location, and (3) that the individuality (...) of a cogniser is inevitably linked with the question of its autonomy, a question ignored by the extended mind hypothesis but for which the enactive approach proposes a precise, operational, albeit non-functionalist answer. The paper raises a pespective of embedded and intersecting forms of autonomous identity generation, some of which correspond to the canonical cases discussed in the extended mind literature, but on the whole of wider generality. In addressing these issues, this paper proposes unbiased, non-species specific definitions of cognition, agency and mediation, thus filling in gaps in the extended mind debates that have led to paradoxical situations and a problematic over-reliance on intutions about what counts as cognitive. (shrink)

This paper explores the ramifications of the extended cognition thesis in the philosophy of mind for contemporary epistemology. In particular, it argues that all theories of knowledge need to accommodate the ability intuition that knowledge involves cognitive ability, but that once this requirement is understood correctly there is no reason why one could not have a conception of cognitive ability that was consistent with the extended cognition thesis. There is thus, surprisingly, a straightforward way of developing our current (...) thinking about knowledge such that it incorporates the extended cognition thesis. (shrink)

When extended cognition is extended into mainstream epistemology, an awkward tension arises when considering cases of environmental epistemic luck. Surprisingly, it is not at all clear how the mainstream verdict that agents lack knowledge in cases of environmental luck can be reconciled with principles central to extended cognition.

The Hypothesis of Extended Cognition (HEC)—that many cognitive processes are carried out by a hybrid coalition of neural, bodily and environmental factors—entails that the intentional states that are reasons for action might best be ascribed to wider entities of which individual persons are only parts. I look at different kinds of extended cognition and agency, exploring their consequences for concerns about the moral agency and personal responsibility of such extended entities. Can extended entities be moral agents (...) and bear responsibility for actions, in addition to or in place of the individuals typically held responsible? What does it mean to be autonomous when one’s cognition is influenced and supported by a milieu of environmental factors? To answer these questions, I explore strong parallels between HEC’s critique of individualism in cognition, and feminist critiques of individualist accounts of self, agency, and autonomy. This relational and social conception of autonomous agency, as scaffolded and supported (or undermined and impaired) by a milieu of social, relational, and normative factors, has important lessons for HEC. Drawing together these two visions of distributed and decentralized aspects of personhood highlights how cognition, action, and responsibility are inextricably linked. It also encourages a reconceptualization of all cognition and all concerns about responsibility for actions, not simply as sometimes extended around individuals, but as fundamentally communal, social, and normative, with individual cognition and individual moral responsibility being derivative special cases, not the paradigm examples. Individuals are merely one of many possible loci of cognition, action, and responsibility. (shrink)

This paper will defend the cognitivist view of cognition against recent challenges from Andy Clark and Richard Menary. It will also indicate the important theoretical role that cognitivism plays in understanding some of the core issues surrounding the hypothesis of extended cognition.

The Credit Theory of Knowledge (CTK)—as expressed by such figures as John Greco, Wayne Riggs, and Ernest Sosa—holds that knowing that p implies deserving epistemic credit for truly believing that p . Opponents have presented three sorts of counterexamples to CTK: S might know that p without deserving credit in cases of (1) innate knowledge (Lackey, Kvanvig); (2) testimonial knowledge (Lackey); or (3) perceptual knowledge (Pritchard). The arguments of Lackey, Kvanvig and Pritchard, however, are effective only in so far as (...) one is willing to accept a set of controversial background assumptions (for instance, that innate knowledge exists or that doxastic voluntarism is wrong). In this paper I mount a fourth argument against CTK, that doesn’t rest on any such controversial premise, and therefore should convince a much wider audience. In particular, I show that in cases of extended cognition (very broadly conceived), the most salient feature explaining S ’s believing the truth regarding p may well be external to S , that is, it might be a feature of S ’s (non-human, artifactual) environment. If so, the cognitive achievement of knowing that p is not (or only marginally) creditable to S , and hence, CTK is false. (shrink)

In a recent contribution to this journal, Andrew Fenton and Sheri Alpert have argued that the so-called “extended mind hypothesis” allows us to understand why Brain Computer Interfaces (BCIs) have the potential to change the self of patients suffering from Locked-in syndrome (LIS) by extending their minds beyond their bodies. I deny that this can shed any light on the theoretical, or philosophical, underpinnings of BCIs as a tool for enabling communication with, or bodily action by, patients with LIS: (...) BCIs are not a case of cognitive extension. I argue that Fenton and Alpert’s claim to the contrary is the result of a widespread confusion about some related, but significantly different, approaches to cognition that all fall under the heading of “situated cognition.” I first provide a short taxonomy of various situated approaches to cognition, highlighting (some of) their important commonalities and differences, which should dissolve some of the confusions surrounding them. Then I show why the extended mind hypothesis is unsuitable as a model of BCI enhancements of LIS patients’ capacity to interact with their surroundings, and I argue that the situated approach with obvious bearings on the sort of questions that were driving Fenton and Alpert is not the idea that cognition is extended , but the idea that cognition is enacted.

The thesis of the extended mind (ExM) holds that the material underpinnings of an individual’s mental states and processes need not be restricted to those contained within biological boundaries: when conditions are right, material artefacts can be incorporated by the thinking subject in such a way as to become a component of her extended mind. Up to this point, the focus of this approach has been on phenomena of a distinctively cognitive nature, such as states of dispositional belief, (...) and processes of planning and calculation. In this paper, we aim to expand the scope of ExM by considering the case for extended affectivity. We begin by clarifying the central commitments of ExM, before investigating its applicability to a range of affective phenomena, both dispositional and occurrent. We argue that proponents of ExM should also accept that the vehicles of emotions, moods, sentiments, temperaments, and character traits can extend beyond skull and skin. (shrink)

The complex systems approach to cognitive science invites a new understanding of extended cognitive systems. According to this understanding, extended cognitive systems are heterogenous, composed of brain, body, and niche, non-linearly coupled to one another. This view of cognitive systems, as non-linearly coupled brain–body–niche systems, promises conceptual and methodological advances. In this article we focus on two of these. First, the fundamental interdependence among brain, body, and niche makes it possible to explain extended cognition without invoking representations (...) or computation. Second, cognition and conscious experience can be understood as a single phenomenon, eliminating fruitless philosophical discussion of qualia and the so-called hard problem of consciousness. What we call “extended phenomenological-cognitive systems” are relational and dynamical entities, with interactions among heterogeneous parts at multiple spatial and temporal scales. (shrink)

According to a standard view, the physical boundary of the person—the skin-and-skull boundary—matters morally because this boundary delineates between where the person begins and the world ends. On the basis of this view we make a distinction between invasive interventions that penetrate this boundary and non-invasive interventions that do not. The development of neuroprosthetics, however, raises questions about the significance of this boundary and the relationship between person and body. In particular it has been argued by appeal to the (...) class='Hi'>Extended Mind thesis that mind and person can extend beyond the body, and hence the skin-and-skull boundary is of questionable significance. In this paper I argue that the Extended Mind thesis is consistent with the ethical relevance of the skin-and-skull barrier. Although it can be argued that cognitive processes and aspect of mind can extend beyond the skin-and-skull boundary as EM claims, it does not follow that the person is also extended beyond this boundary. The moral sense of person is closely related to the notion of person as a subject of experiences and this, in turn, is related to the sensory and somatosensory aspects of the body. The development of neuroprosthetics provides us with reason to see that persons can be variously embodied, but this is consistent with the functional and ethical significance of the skin-and-skull boundary.

The general idea of enactive perception is that actual and potential embodied activities determine perceptual experience. Some extended mind theorists, such as Andy Clark, refute this claim despite their general emphasis on the importance of the body. I propose a compromise to this opposition. The extended mind thesis is allegedly a consequence of our commonsense understanding of the mind. Furthermore, extended mind theorists assume the existence of non-human minds. I explore the precise nature of the commonsense understanding (...) of the mind, which accepts both extended minds and non-human minds. In the area of philosophy of mind, there are two theories of intentionality based on such commonsense understandings: neo-behaviorism defended, e.g., by Daniel Dennett, and neo-pragmatism advocated, e.g., by Robert Brandom. Neither account is in full agreement with how people ordinarily use their commonsense understanding. Neo-pragmatism, however, can overcome its problem—its inability to explain why people routinely find intentionality in non-humans—by incorporating the phenomenological suggestion that interactional bodily skills determine how we perceive others’ intentionality. I call this integrative position embodied neo-pragmatism . I conclude that the extended view of the mind makes sense, without denying the existence of non-human minds, only by assuming embodied neo-pragmatism and hence the general idea of enactive perception.

In the six decades since the publication of Julian Huxley's Evolution: The Modern Synthesis, spectacular empirical advances in the biological sciences have been accompanied by equally significant developments within the core theoretical framework of the discipline. As a result, evolutionary theory today includes concepts and even entire new fields that were not part of the foundational structure of the Modern Synthesis. In this volume, sixteen leading evolutionary biologists and philosophers of science survey the conceptual changes that have emerged since Huxley's (...) landmark publication, not only in such traditional domains of evolutionary biology as quantitative genetics and paleontology but also in such new fields of research as genomics and EvoDevo. Most of the contributors to Evolution—The Extended Synthesis accept many of the tenets of the classical framework but want to relax some of its assumptions and introduce significant conceptual augmentations of the basic Modern Synthesis structure—just as the architects of the Modern Synthesis themselves expanded and modulated previous versions of Darwinism. This continuing revision of a theoretical edifice the foundations of which were laid in the middle of the nineteenth century—the reexamination of old ideas, proposals of new ones, and the synthesis of the most suitable—shows us how science works, and how scientists have painstakingly built a solid set of explanations for what Darwin called the "grandeur" of life.

This paper explores several paths a distinctive third wave of extended cognition might take. In so doing, I address a couple of shortcomings of first- and second-wave extended cognition associated with a tendency to conceive of the properties of internal and external processes as fixed and non-interchangeable. First, in the domain of cognitive transformation, I argue that a problematic tendency of the complementarity model is that it presupposes that socio-cultural resources augment but do not significantly transform the brain’s (...) representational capacities during diachronic development. In this paper I show that there is available a much more dynamical explanation—one taking the processes of the brain’s enculturation into patterned practices as transforming the brain’s representational capacities. Second, in the domain of cognitive assembly, I argue that another problematic tendency is an individualistic notion of cognitive agency, since it overlooks the active contribution of socio-cultural practices in the assembly process of extended cognitive systems. In contrast to an individualistic notion of cognitive agency, I explore the idea that it is possible to decentralize cognitive agency to include socio-cultural practices. (shrink)

The growing prominence of computers in contemporary life, often seemingly with minds of their own, invites rethinking the question of moral responsibility. If the moral responsibility for an act lies with the subject that carried it out, it follows that different concepts of the subject generate different views of moral responsibility. Some recent theorists have argued that actions are produced by composite, fluid subjects understood as extended agencies (cyborgs, actor networks). This view of the subject contrasts with methodological individualism: (...) the idea that actions are produced only by human individuals. This essay compares two views of responsibility: moral individualism (the ethical twin of methodological individualism), and joint responsibility (associated with extended agency theory). It develops a view of what joint responsibility might look like, and considers the advantages it might bring relative to moral individualism as well as the objections that are sure to be raised against it.

An extended scale relativity theory, actively developed by one of the authors, incorporates Nottale's scale relativity principle where the Planck scale is the minimum impassible invariant scale in Nature, and the use of polyvector-valued coordinates in C-spaces (Clifford manifolds) where all lengths, areas, volumes⋅ are treated on equal footing. We study the generalization of the ordinary point-particle quantum mechanical oscillator to the p-loop (a closed p-brane) case in C-spaces. Its solution exhibits some novel features: an emergence of two explicit (...) scales delineating the asymptotic regimes (Planck scale region and a smooth region of a quantum point oscillator). In the most interesting Planck scale regime, the solution recovers in an elementary fashion some basic relations of string theory (including string tension quantization and string uncertainty relation). It is shown that the degeneracy of the first collective excited state of the p-loop oscillator yields not only the well-known Bekenstein–Hawking area-entropy linear relation but also the logarithmic corrections therein. In addition we obtain for any number of dimensions the Hawking temperature, the Schwarschild radius, and the inequalities governing the area of a black hole formed in a fusion of two black holes. One of the interesting results is a demonstration that the evaporation of a black hole is limited by the upper bound on its temperature, the Planck temperature. (shrink)

This article explores the notion of the Web-extended mind, which is the idea that the technological and informational elements of the Web can sometimes serve as part of the mechanistic substrate that realizes human mental states and processes. It is argued that while current forms of the Web may not be particularly suited to the realization of Web-extended minds, new forms of user interaction technology as well as new approaches to information representation do provide promising new opportunities for (...) Web-based forms of cognitive extension. In addition, it is suggested that extended cognitive systems often rely on the emergence of social practices and conventions that shape how a technology is used. Web-extended minds may thus depend on forms of socio-technical co-evolution in which social forces and factors play just as important a role as do the processes of technology design and development.

In recent years, philosophical developments of the notion of distributed and/or scaffolded cognition have given rise to the “extended mind” thesis. Against the popular belief that the mind resides solely in the brain, advocates of the extended mind thesis defend the claim that a significant portion of human cognition literally extends beyond the brain into the body and a heterogeneous array of physical props, tools, and cultural techniques that are reliably present in the environment in which people grow, (...) think, and act (Clark and Chalmers 1998; Clark 1997, 2003, 2008; Wilson 2004; Rowlands 1999, 2012; Menary 2007; Theiner 2011). However, as commentators who are friendly to the idea of distributed cognition have pointed out, the philosophical debate over extended cognition has predominantly focused on the impact of tools on our thinking while somewhat neglecting the distinctively social and cultural dimensions of cognitive scaffolding (Sterelny 2004, 2010; Caporael 1997a, 1997b; Smith and Semin 2004; Wilson 2005; Barnier et al. 2008; Sutton et al. 2010; Theiner, Allen, and Goldstone 2010). -/- To reorient the reigning paradigm, Hutchins (2010, 445) has recently proposed the “hypothesis of enculturated cognition” (HEnC) as an alternative to Clark’s (2003, 2008) largely individualistic vision of the extended mind. According to the HEnC, the “ecological assemblies of human cognition make pervasive use of cultural products” and are typically “assembled … in ongoing cultural practices” (ibid.). Cultural practices, for Hutchins, are essentially “the things people do in interaction with one another” (ibid., 440). My goal in this chapter is to follow up on Hutchins’s call to “spur the program forward” (ibid., 445), by generalizing Kirsh and Maglio’s (1994) distinction between pragmatic and epistemic actions from the level of individuals to the level of groups. The concept of a collective epistemic action refers to the ways in which groups of people actively change the structure of their social organization, with the epistemic goal of reshaping and augmenting their cognitive performance as integrated collectivities. By placing a renewed emphasis on the interactions between people, rather than between people and their tools, I hope to reconnect the cognitive-scientifically-driven “extended mind” thesis with complementary areas of social-scientific research in which groups are analyzed as the seats of action and cognition in their own right. In particular, the literature to which I aim to build a bridge in this paper is, on the one hand, certain segments of social and organizational psychology (Larson and Christensen 1993; Hinsz et al. 1997; Mohammed and Dumville 2001), and, on the other hand, theories of collective and institutional action (Ostrom 1990; List and Pettit 2011).

This paper explains why Clark’s Extended Mind thesis is not capable of sufficiently grasping how and in what sense external objects and technical artifacts can become part of our human cognition. According to the author, this is because a pivotal distinction between inside and outside is preserved in the Extended Mind theorist’s account of the relation between the human organism and the world of external objects and artifacts, a distinction which they proclaim to have overcome. Inspired by Charles (...) S. Peirce’s philosophy of mind, in particular, the author tries to find a way out of this ‘inside–outside’ fallacy. External objects, artifacts or processes should, according to him, not be conceived as inanimate and unintelligent matter utilised by a separately living, inner mental sphere that has set certain pre-established goals for itself. Mind has rather an artifactual character. It is not extended by an inner biological cognitive core but rather unfolds itself through objects and artifacts. Mind as such is, especially in our modern technological culture, shaped by virtue of and through technical artifacts. Recognizing this artifactual dimension of mind will, the author concludes, enable a more critical analysis of contemporary claims that ascribe certain original and irreducible features to thinking.

In his paper, in this journal, Sterelney (Phenomenology and the Cognitive Sciences 9:465–481, 2010) claims that cases of extended mind are limiting cases of environmental scaffolding and that a niche construction model is a more helpful, general framework for understanding human action. He further claims that extended mind cases fit into a corner of a 3D space of environmental scaffolds of cognitive competence. He identifies three dimensions which determine where a resource fits into this space and suggests that (...)extended mind models seem plausible when a resource is highly reliable, individualised/entrenched and a single-user resource. Sterelney also claims that the most important cognition-enhancing resources are provided collectively by one generation to the next. In this paper, I argue that Sterelney is both right and wrong and this because he focuses primarily on external, physical resources and construes scaffolding as exclusively unidirectional and diachronic. Using examples of unfamiliar tool use, visual processing and human emotional ontogenesis, I argue, respectively, that extended mind cases include those which fail to meet Sterelney’s dimensional criteria; that the most important cognition—enhancing resources are those which actually build brains; that these are provided on a one-to-one basis in emotional ontogenesis; and, this depends on bidirectional and synchronic (if disproportionate) cognitive scaffolding.

I critically assess two widely cited evolutionary biological arguments for two versions of the ‘Extended Mind Thesis’ (EMT): namely, an argument appealing to Dawkins’s ‘Extended Phenotype Thesis’ (EPT) and an argument appealing to ‘Developmental Systems Theory’ (DST). Specifically, I argue that, firstly, appealing to the EPT is not useful for supporting the EMT (in either version), as it is structured and motivated too differently from the latter to be able to corroborate or elucidate it. Secondly, I extend and (...) defend Rupert’s argument that DST also fails to support or elucidate the EMT (in either version) by showing that the considerations in favour of the former theory have no bearing on the truth of the latter. I conclude by noting that the relevance of this discussion goes beyond the debate surrounding the EMT, as it brings out some of the difficulties of introducing evolutionary biological considerations into debates in psychology and philosophy more generally.

For Descartes, minds were essentially non-extended things. Contemporary cognitive science prides itself on having exorcised the Cartesian ghost from the biological machine. However, it remains committed to the Cartesian vision of the mental as something purely inner. Against the idea that the mind resides solely in the brain, advocates of the situated and embodied nature of cognition have long stressed the importance of dynamic brain-body-environment couplings, the opportunistic exploitation of bodily morphology, the strategic performance of epistemically potent actions, the (...) generation and use of external representations, and the cognitive scaffolding provided by artifacts and social-cultural practices. According to the “extended mind” thesis, a significant portion of human cognition literally extends beyond the brain into the body and its environment. My goal in this book is to clarify the nature and scope of this thesis, and to defend its central insight that cognition is not confined to the boundaries of the biological individual. (shrink)

Recent social theory has departed from methodological individualism’s explanation of action according to the motives and dispositions of human individuals in favor of explanation in terms of broader agencies consisting of both human and nonhuman elements described as cyborgs, actor-networks, extended agencies, or distributed cognition. This paper proposes that moral responsibility for action also be vested in extended agencies. It advances a consequentialist view of responsibility that takes moral responsibility to be a species of causal responsibility, and it (...) answers objections that might be raised on the basis of intentions and deserts.

In this paper we explore the potential bearing of the extended mind thesis—the thesis that the mind extends into the world—on epistemology. We do three things. First, we argue that the combination of the extended mind thesis and reliabilism about knowledge entails that ordinary subjects can easily come to enjoy various forms of restricted omniscience. Second, we discuss the conceptual foundations of the extended mind and knowledge debate. We suggest that the theses of extended mind and (...)extended knowledge lead to a bifurcation with respect to the concepts of belief and knowledge. We suggest that this conceptual bifurcation supports a form of pluralism about these concepts. Third, we discuss whether something similar can be said at the metaphysical level. (shrink)

I offer a preliminary defense of the hypothesis of extended emotions . After discussing some taxonomic considerations, I specify two ways of parsing HEE: the hypothesis of bodily extended emotions , and the hypothesis of environmentally extended emotions . I argue that, while both HEBE and HEEE are empirically plausible, only HEEE covers instances of genuinely extended emotions. After introducing some further distinctions, I support one form of HEEE by appealing to different streams of empirical research—particularly (...) work on music and emotion regulation. However, I register skepticism about a second and more radical form of HEEE. (shrink)

In this article we argue that the classical—linear and bottom-up directed—models of causation in biology, and the ‘‘proximate/ultimate’’ dichotomy, are inappropriate to capture the complexity inherent to biological processes. We introduce a new notion of ‘‘multilevel causation’’ where old dichotomies such as proximate/ultimate and bottom-up/ top-down are reinterpreted within a multilevel, web-like, approach. In briefly reviewing some recent work on complexity, EvoDevo, carcinogenesis, autocatalysis, comparative genomics, animal regeneration, phenotypic plasticity, and niche construction, we will argue that such reinterpretation is a (...) necessary step for the advancement of the ‘‘Extended Synthesis.’’.

In my dissertation, I explore the remarkable talent of human beings to modify and co-opt resources of their material and socio-cultural environment, and integrate them with their biological capacities in order to enhance their cognitive prowess. In the first part, I clarify and defend the claim – known as the extended mind thesis – that a significant portion of human cognition literally extends beyond the head into the world, actively incorporating our bodies and an intricate web of material resources (...) (Clark, 2003, 2008; Wilson, 2004). Yet since much of distinctively human cognition occurs when we think in groups, I argue that the bias of this thesis to view cognition as an essentially solitary (albeit bodily or technologically extended) activity is misplaced. In the second part, I re-deploy the idea of cognitive extensions to establish a scientifically respectable version of the group mind thesis – i.e., the claim that groups can have emergent cognitive properties and capacities in their own right.

While the extended cognition (EC) thesis has gained more followers in cognitive science and in the philosophy of mind and knowledge, our main goal is to discuss a different area of significance of the EC thesis: its relation to philosophy of science. In this introduction, we outline two major areas: (I) The role of the thesis for issues in the philosophy of cognitive science, such as: How do notions of EC figure in theories or research programs in cognitive science? (...) Which versions of the EC thesis appear, and with which arguments to support them? (II) The potentials and limits of the EC thesis for topics in general philosophy of science, such as: Can naturalism perhaps be further advanced by means of the more recent EC thesis? Can we understand “big science” or laboratory research better by invoking some version of EC? And can the EC thesis help in overcoming the notorious cognitive/social divide in science studies?

The place of social epistemology within contemporary philosophy, as well as its relation to other academic disciplines, is the topic of an ongoing debate. One camp within that debate holds that social epistemology should be pursued strictly from within the perspective of individualistic analytic epistemology. In contrast, a second camp holds that social epistemology is an interdisciplinary field that should be given priority over traditional analytic epistemology, with the specific aim of radically transforming the latter to fit the results and (...) methodology of the former. We are rather suspicious of this apparent tension, which we believe can be significantly mitigated by paying attention to certain recent advances within philosophy of mind and cognitive science. Accordingly, we attempt to explain how extended knowledge, the result of combining active externalism from contemporary philosophy of mind with contemporary epistemology, can offer an alternative conception of the future of social epistemology.

Superluminal particles are studied within the framework of the Extended Relativity theory in Clifford spaces (C-spaces). In the simplest scenario, it is found that it is the contribution of the Clifford scalar component π of the poly-vector-valued momentum which is responsible for the superluminal behavior in ordinary spacetime due to the fact that the effective mass $\mathcal{M} = \sqrt{ M^{2} - \pi^{2} }$ is imaginary (tachyonic). However, from the point of view of C-space, there is no superluminal (tachyonic) behavior (...) because the true physical mass still obeys M 2>0. Therefore, there are no violations of the Clifford-extended Lorentz invariance and the extended Relativity principle in C-spaces. It is also explained why the charged muons (leptons) are subluminal while its chargeless neutrinos may admit superluminal propagation. A Born’s Reciprocal Relativity theory in Phase Spaces leads to modified dispersion relations involving both coordinates and momenta, and whose truncations furnish Lorentz-violating dispersion relations which appear in Finsler Geometry, rainbow-metrics models and Double (deformed) Special Relativity. These models also admit superluminal particles. A numerical analysis based on the recent OPERA experimental findings on alleged superluminal muon neutrinos is made. For the average muon neutrino energy of 17 GeV, we find a value for the magnitude $|\mathcal{M } | = 119.7\mbox{~MeV}$ that, coincidentally, is close to the mass of the muon m μ =105.7 MeV. (shrink)
